AirTAC GFC300-15 Combination Unit (GFC30015MNK)
The AirTAC AirTAC GFC300-15 Combination Unit (GFC30015MNK) is a genuine G-series two-unit air-preparation set: a filter regulator that filters and regulates in one body, coupled to a lubricator. Two bodies do the work of three, with PT1/2" ports, a 40 µm element, a manual drain and regulation over 0.05 - 0.9 MPa (7 - 130 psi).

About the AirTAC GFC300-15 Combination Unit (GFC30015MNK)
The AirTAC GFC30015MNK is a two-unit air preparation set - a filter-regulator plus a separate lubricator - in the 300 size with PT1/2 ports and a reverse (check) valve fitted, shown by the K code. The filter bowl is drained manually, filtration is the standard 40 um element, and the regulator in this manual-drain configuration adjusts over 0.05-0.9 MPa (7-130 psi). The lubricator meters oil mist into the regulated air for downstream actuators and tools. Maximum working pressure is 1.0 MPa (145 psi), the bowl is PC (polycarbonate) as is standard at size 300, and operating temperature is -5 to 70 C (non-freezing). No gauge is fitted on this variant.
This is a genuine AirTAC part. The GFC series is offered in sizes 200 through 600 with drain-type, filter-grade, gauge, reverse-valve and G/NPT thread options listed in the catalogue. Flow figures are published as curves rather than a single rating, so ask us to confirm the datasheet flow data for your circuit.

Specifications follow the official AirTAC G-series air-preparation data. The regulating band is set by the drain type: automatic and differential-pressure drains regulate 0.15 - 0.9 MPa, a manual drain regulates 0.05 - 0.9 MPa. Standard type, regulating 0.05 - 0.9 MPa (7 - 130 psi). The set has no separate bracket code — the two units couple together with their own mounting hardware. Flow curves, weight and outline dimensions are not published in our data set — ask us and we will confirm from the factory datasheet.
Model Code: AirTAC GFC300-15 Combination Unit (GFC30015MNK)
| GFC300 | G-series two-unit set, 300 body — sets the port range. |
|---|---|
| 15 | Port size PT1/2". This body offers 08 = PT1/4", 10 = PT3/8", 15 = PT1/2". |
| M | Drain: Manual drain — this also sets the regulating band (0.05 - 0.9 MPa (7 - 130 psi)). |
| (blank) | Standard type. Blank is standard, L is the low-pressure type. |
| N | No pressure gauge (N). |
| (blank) | Gauge shape: Factory standard. C is round, F is square. |
| (blank) | Gauge scale: Factory standard. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| (blank) | PT thread. PT is the default; G is BSPP and T is NPT. |
| K | Reverse-flow (reflux) valve fitted. |
Field order is size, port, drain, type, gauge, shape, scale, grade, thread, reflux — there is no bracket position on a combination set. Constituent units, orderable separately as spares: GFR300-15 filter regulator and GL300-15 lubricator.
Size Class & How It Differs From GC
- GFC200PT1/8" - PT1/4"
- GFC300PT1/4" - PT1/2"
- GFC400PT3/8" - PT1/2"
- GFC600PT3/4" - PT1"
A GFC is two units because filtering and regulating share one body. A GC is three separate units — filter, regulator and lubricator. Both filter, regulate and lubricate; the GFC is the shorter assembly, the GC keeps the filter and regulator serviceable as separate bodies.

Where the AirTAC GFC300-15 Combination Unit (GFC30015MNK) Is Used
Press fixture clamping supply
Conditions air feeding clamping cylinders on a press-fit fixture station. The fitted reverse (check) valve is included for circuits where the designer wants check-valve protection in the supply line, while the set filters, regulates and lubricates the clamp air.
Pneumatic valve manifold feed
Prepares the air entering a directional-valve manifold on a machine skid: 40 um filtration ahead of a regulated, lubricated supply keeps spool valves clean and moving freely, with manual bowl draining tied to the shift maintenance round.
Textile machine air service
Serves the PT1/2 air drop feeding doffing and yarn-threading actuators on a textile machine. The regulator holds the set pressure, the lubricator mists oil to the actuators, and the K-code check valve is fitted as specified for the machine build.
Is the AirTAC GFC300-15 Combination Unit (GFC30015MNK) the Right Set?
Use this code when your decodable requirements are: 300 size, PT1/2 port, manual drain, standard 40 um filtration, no gauge, and a reverse (check) valve fitted - the K suffix is the only difference from the plain GFC30015MN. If you do not need backflow protection in the circuit, the non-K code is the equivalent unit without the valve. Larger sizes (400, 600) step up port and flow capacity; the W code switches the element to 5 um. Thread is PT as standard with G (BSPP) and NPT variants orderable.
Because flow is published as curves and not as a single rating, send us your application details and we will confirm sizing from the datasheet before you order.
Quick checklist
- ✓ Body size for your peak flow (PT1/2" here)
- ✓ Element 40 µm or 5 µm
- ✓ Drain sets the regulating band
- ✓ Gauge fitted, shape and scale
- ✓ Two-unit (GFC) or three-unit (GC) layout
- ✓ Oil mist acceptable downstream
Installation & Maintenance Notes
- check Install with the airflow arrow: filter regulator first, lubricator last.
- check Mount vertically, bowls down.
- check Keep inlet pressure at or below 1.0 MPa (145 psi).
- check Adjust only within 0.05 - 0.9 MPa (7 - 130 psi).
- check Drain condensate before the bowl fills; check the oil level.
- check Keep the set above freezing (-5 to +70 °C, unfreeze).
The PC bowls must not be cleaned with solvents — wipe them with a dry cloth. The lubricator adds an oil mist downstream, so if any branch must stay oil-free, take that branch off before the lubricator or use a GFR300-15 filter regulator on its own.
AirTAC GFC300-15 Combination Unit (GFC30015MNK) FAQ
Rated flow is published as curves, not as one rated number, so the honest way to size it is against your actual demand. Send us your flow, pressure and duty cycle and we will confirm the GFC30015MNK data from the AirTAC datasheet on request.
K means a reverse (check) valve is fitted to the unit. It is the same two-unit filter-regulator-plus-lubricator set as the GFC30015MN otherwise - PT1/2, size 300, manual drain, 40 um element, no gauge. For the valve's exact behaviour in your circuit, ask us for the datasheet.
